I looked at variable speed pumps last year when my 1-1/2HP motor burned up. Being in southern OH I could not justify it for my 12-14 week swimming season. When I have to replace the pump I will take another look.

That said you guys have me thinking I am throwing money away by running 24/7.

I am sure I would have to make adjustments to my chlorine feeder(3" tri-chlor tabs).

Can you think of any other potential problems I should watch for?
